Based on annual driving of 15,000 miles and fuel efficiency of 20 mpg, a car in the United States uses, on average, 750 gallons of gasoline per year. If annual automobile fuel usage is normally distributed, and if 21.77% of cars in the United States use less than 500 gallons of gasoline per year, what is the standard deviation?

Fuel efficiency, measured in miles per gallon, for many vehicles follows a symmetric and bell shaped distribution. Suppose the city driving fuel efficiency of a 2009 Honda Odyssey has an average of 17mpg with a standard deviation of 2.2 mpg. What percentage of 2009 Honda Odysseys have a fuel efficiency between 12.6mpg and 19.2mpg? Answer:???

Dylan Jones kept careful records of the fuel efficiency of his new car. After the first twelve times he filled up the tank, he found the mean was 26.1 miles per gallon (mpg) with a sample standard deviation of 1.0 mpg. Compute the 98% confidence interval for his mpg. How many times should he fill his gas tank to obtain a margin of error below 0.15 mpg?
